BROILER.

Application filed May 15,

To all whom it may concern Be it known that I, Amen M. Knnsrmw, a citizen of the United States, residing at Cambridge, in the county of Middlesex and a State of Massachusetts, have invented certain new and useful Inun'ovements in Broilers; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

My invention relates to broilers of the gridiron type in which there is a lower grid over which is superimposed an upper grid, each having grooved or concave bars and intervening open spaces, the bars and open spaces of one grid alternating with the open spaces and bars of the other grid, and the upper grid being separable from the lower grid.

The present invention has for its object to provide improved features of construction of the lower grid whereby the same will be materially strengthened and the liability of the middle portion to fracture due to contraction and expansion of the junction be tween the adjacent ends of the bars as heretofore disposed is materially lessened.

To the accomplishment of the foregoing and such other objects as may hereinafter appear the invention contemplates forming the middle or central portion of the grid of a web with arms or members radiating from a common center, substantially at right angles to one another, with the opposite sides of each of the radiating members depressed to form grooves extending parallel with the intermediate portion of each arm. Associated with the central web formed as specified are grooved ribs, each of a V-shaped formation, which alternate with intervening open spaces. Other features of novel construction will be hereinafter specified.

In the drawing illustrating the preferred embodiment of the invention Figure 1 is a plan view of the complete broiler;

Figure 2 is a vertical cross-section on line 22 of Figure 1;

Figure 3 is a detail, perspective fragmentary view of the upper and lower grids;

Figure 4 is a cross'section on line -flt of Figure 1;

Figure 5 is a plan view of the lower Figure 6 is a plan view of the upper grid;

Figure 7 is a detail, perspective, fragmentary view of the upper and lower grids;

Figure 8 is a sectional view on line 8 8 of Figure 1.

In the drawings the numeral 1 designates the base or lower grid member of the broiler and'2 the upper or top member, separable one from the other. Under the present invention the lower member is composed of a centrally disposed web 3 having wings or branches 4 radiating from the center outwardly, and each wing formed at each side of its longitudinally extending central portion 5 with channels or grooves (3. The spaces between the radiating wings 4 are occupied by channeled or grooved bars 7 each of a V-shaped form as shown and disposed so as to leave intervening open spaces 8 between the bars. It is preferred to make the under face of the longitudinally extending central portions of the radiating wings concave as indicated at 9 so that the flame striking the under side of the wings will be directed lengthwise of the wings and thus obtain a better diffusion of the heating flame over the under side of the grid. By pro viding the centrally disposed web having the radiating wings the grid is braced and strengthened, and the liability to fracture due to the intensity of the flame orheat and contraction and expansion is minimized over the form where the converging ends of independent grooved bars are group-ed at the center of the grid as heretofore has been customary, and at the same time channels are provided at each side of the wings of the web to receive the drippings from the meat on the top member of the grid.

The upper grid member 2 of the broiler is formed of a number of grooved or channeled bars or ribs 10 of. a V-shaped formation as shown and disposed so as to leave intervening open spaces 11, the channeled ribs 10 lying above the open intervening spaces of the lower grid when the two grids are assembled as illustrated in Figures I and 2 of the drawing.

In order to space the upper grid from the lower grid, the upper one is formed with depending feet 12 disposed one opposite to the other and preferably in a line central grid lltl

with the handle 13 of the lower grid, and for these feet are provided seats 14f formed on the lower grid as indicated in Figures 2, 5, 7 and 8 of the drawing.

For the purpose of preventing the upper grid from rotating on the lower grid, and also to prevent the upper grid from tilting and dropping from the lower grid when the broiler is positioned edge-nip, either inthe suspension of the broiler, or in tilting the same for ouring from the annular gutter 15 the meat extracts or juices re-' eeived theieimfronrthe channelled or grooved bars or ribs; 1" for'n'i the upper grid with depending lugs? 16, disposed opposite each other, at opposite'sides of the grid, adapted to fit in openings 1'? formed in'tlie lower grid and of a width. to bear against the o13positewalls of the openings, and from the perimeter of the grid adjacent; to the lugs'16, are formed depending lugs'18 which will bear against opposite sides of bosses 19 formed onthe lower grid, the lugs is resting on SeatsQO at the opposite sides of the bosses 19, as illustrated in Figures 3 and 4 of the drawing. It will be observed that the space between lugs and I8 taken together forins a cirotcl'i that receives the edge of the lower grid at the inner wall of the gutter atth'e' points where the s outs 21' of the gutter 1 5 arelocated, so thatwhen' the grids aretilted for pouring the juices from the gutter the. upper grid will be prevented from dropping away from the lower grid. It will also be observed that by having the sides of the lugs 16' bear against the opposite side walls of the openings inwhich they fit, and having the lugs 18 bear against" the opposite sides of the bosses 1-9 the upper grid is" held against any" r'otatix 'e movement what soever relative to the lower grid and thus the possibilitv "1"; tli'eupper 'id slid-ingfrom position i sjpositively pre've I have showi and described in detailthe' preferred construction of the several parts but ism" he understood that changes in some oil. the parts may be mane; without departing from the essential features sought to he definedinf the appended claims.

Having described my invention" and set forth its meritswhat I claim is:

1. A broiler consisting of two gi' 'ids,"s eparable one 'froin'the other, one grid including a' web comprising branches radiating from ztce'nter, eaclrbrancli having a channel formed therein alon side the central longitudinally extending portion of the branch, andchann'e-led bars disposed tole'a've interve'iiin'g open spares between the bars,

*face, and cl'iai'ineled bars disposed to leave intervening open spaces between" them; the other grid being formed" with channeled bars spaced apart to leave intervening openspa'ces between tliein, the open intervening spaces of one grid registering with the channeled portions of the other grid;

3. A broiler consisting of two grld's, one

separable from the other, both grids having channeled bar's spaced apart to leave intervenin'g open spaces between the bars a'ind disposed so thatthe intervening open spaces of one grid willfregist er with the channeled bars of the other grid, one of the grids being provided with depending lugs spacedf apart to form a crotch; between them and located at opposite sides of the grid; the other grid" being formed with openings to receive the innermost of the crotch-forining lugs and With bosses for the outermost lugs to engage to prevent tilting and rotativc movement of one grid relatively to the other. v

4. A broiler" consisting of two grids, one separablefrom the other, both" grids having channeled" bars spaced apart to leave intervening openspaces between the bars and disposed so that the intervei'iing open spaces of one grid will register with the oliann e'led'hzrs of the other grid, client the grids having an an inilar perip'lieral trough provided: with o1)1;i os:i telv"disposeddischarge spouts, the other grid heii'ig Formed with depending lugs; disposed to other openings in the" companion grid opposite the spouts to the annular troii gh and formed with other depending lugs intermediate of the first mentioned lugs and adapted to; rest upon seats therefor fol-mar in the other grid to space one grid from the" other;

In testimony whereof I' my sig'na turein'presenc'e of two witnesses.
